So you’ve decided to finally write a will in Washington. Congratulations on acknowledging your own mortality. Most people can’t even manage that. Here’s what WA law requires to make sure your last wishes actually hold up in court instead of becoming an expensive piece of creative writing.
The basic requirements
Washington requires 2 witnesses to make your will valid. Good news: Washington doesn’t require a notary for your will, though getting one makes it self-proving and saves your executor a headache later. You must be at least 18 years old and of sound mind, though if you’ve been putting this off for years, the “sound mind” part is debatable.
Washington supports self-proving affidavits, which means if you get your witnesses to sign a sworn statement with a notary, they won’t have to show up in court later to confirm they watched you sign. Future-you’s executor will thank present-you.
Handwritten and electronic wills
Washington does NOT accept holographic (handwritten) wills, so put down the napkin and the crayon. Washington is one of the forward-thinking states that accepts electronic wills. Welcome to the future of death planning.
What Washington law says about your stuff
As a community property state, your spouse already owns half of everything acquired during the marriage. Your will covers your half and any separate property. Under Wash. Rev. Code §11.12.020, if you die without a will in Washington, your assets get distributed according to intestacy laws, basically, the state’s default settings for dead people. These defaults rarely match what anyone actually wants.
The bottom line
A valid will in Washington isn’t complicated, but it does need to follow the rules. 2 witnesses, your signature, and a clear head. Skip any of these and you might as well not bother, your family will be stuck in probate court arguing about who gets the good china while lawyers bill $300 an hour to watch.
